The aliquots used in the study were taken from commercial AI Artificial Insemination doses. The aim of the study was to determine the effect of season on sperm quality parameters. Motility increased in the August samples compared to the samples from April and May, the superoxide production decreased. Proverna analyserades med avseende på koncentration, progressiv motilitet, total motilitet, andel spermier med normal morfologi, viabilitet med SYBR och Hoechst, produktion av superoxid O2-produktion av väteperoxid H2O2 samt kromatinintegritet SCSA. Forskningen på området är begränsad och består ofta av studier med litet underlag eller retrospektiva studier där skötselfaktorer och stoegenskaper kan inverka.

Since motility has been closely linked to fertility one could conclude that stallion fertility may be higher by the end of the breeding season.

Sperm Capacitation

Sveriges lantbruksuniversitet Swedish University of Agricultural Sciences. Att försöka förutse ett handjurs fertilitet är komplext, inte minst då spermieegenskaperna skiljer sig åt mellan hingstar och även mellan ejakulat från samma hingst. Samples were collected at four times during two consecutive weeks in April and May, which is in the first third of the Swedish breeding season, and then again four times during two weeks in August which is the end of the breeding season. I studien analyserades ordinarie transportspermadoser från nio hingstar av halvblodsras. The large number of factors influencing the outcome of a mating complicates fertility prediction.
